This study aimed to investigate the prevalence and factors associated with work-related musculoskeletal disorders among cashiers in small-scale businesses in Northwestern Ethiopia.
A multicentre cross-sectional study was conducted from July to September 2022. The data were collected using a validated and standardised Nordic Musculoskeletal Questionnaire. The collected data were entered into EpiData V.4.6 and analysed using Stata V.14. A multivariable logistic regression analysis was used to ascertain the significance of associations at p<0.05 and the adjusted OR (AOR) with a 95% CI.
The study was conducted in small-scale businesses in the North Gondar Zone.
A total of 618 cashiers participated in this study.
The primary outcome of the study is the prevalence of work-related musculoskeletal disorders, which was measured using the Nordic Musculoskeletal Questionnaire.
The response rate was 97.5% (N=618). The majority (373; 60.4%) of the study participants were female. The mean (±SD) age of the participants was 30 (±8.3) years. The prevalence of work-related musculoskeletal disorders during the last 12 months was found to be 75.4% (n=466) (95% CI 71.8%, 78.8%). Marital status (married) (AOR=2.12; 95% CI 1.26, 3.56), lack of physical exercise (AOR=2.07; 95% CI 1.32, 3.23), alcohol consumption (AOR=3.55; 95% CI 2.18, 5.78) and awkward work posture (AOR=2.40; 95% CI 1.43, 4.0) were significant factors associated with work-related musculoskeletal disorders among sampled cashiers.
This study concluded that the overall prevalence of work-related musculoskeletal disorders was high among cashiers in small-scale businesses. Being married, a lack of physical exercise, alcohol consumption and awkward work posture were significant factors of work-related musculoskeletal disorders. To reduce work-related musculoskeletal disorders, it is recommended taking part in physical activity, avoiding alcohol consumption and avoiding awkward work posture.
本研究旨在调查埃塞俄比亚西北部小型企业收银员中与工作相关的肌肉骨骼疾病的患病率和相关因素。
这是一项 2022 年 7 月至 9 月进行的多中心横断面研究。使用经过验证和标准化的北欧肌肉骨骼问卷收集数据。收集的数据输入 EpiData V.4.6 并使用 Stata V.14 进行分析。使用多变量逻辑回归分析确定 p<0.05 时关联的显著性和具有 95%置信区间的调整优势比 (AOR)。
研究在北贡德尔地区的小型企业中进行。
共有 618 名收银员参加了这项研究。
本研究的主要结果是使用北欧肌肉骨骼问卷测量的与工作相关的肌肉骨骼疾病的患病率。
应答率为 97.5%（N=618）。大多数（373；60.4%）研究参与者为女性。参与者的平均（±SD）年龄为 30（±8.3）岁。在过去 12 个月中，与工作相关的肌肉骨骼疾病的患病率为 75.4%（n=466）（95%CI 71.8%，78.8%）。婚姻状况（已婚）（AOR=2.12；95%CI 1.26，3.56）、缺乏体育锻炼（AOR=2.07；95%CI 1.32，3.23）、饮酒（AOR=3.55；95%CI 2.18，5.78）和不适当的工作姿势（AOR=2.40；95%CI 1.43，4.00）是收银员与工作相关的肌肉骨骼疾病的显著相关因素。
本研究得出的结论是，小型企业收银员中与工作相关的肌肉骨骼疾病的总体患病率很高。已婚、缺乏体育锻炼、饮酒和不适当的工作姿势是与工作相关的肌肉骨骼疾病的显著因素。为了减少与工作相关的肌肉骨骼疾病，建议参加体育活动、避免饮酒和避免不适当的工作姿势。
